Petra Diamonds Ltd., a producer of the gems in southern Africa, said there are signs of a recovery in demand after prices of unpolished stones slumped this year.
“The market is not that bad,” Chief Executive Officer Johan Dippenaar said in a telephone interview. “There are definitely some green shoots out there. We see good attendance at our tenders.”
Petra sells through auctions, or tenders, in Johannesburg and Antwerp. Unpolished, or rough, diamond prices have fallen about 19 percent this year, according to PolishedPrices.com, as Asian buying slowed and the euro crisis eroded consumption of the gems. Prices rose more than 20 percent in each of the past three years as producers struggled to keep pace with demand.
“If people realize Europe is not going to be a real doomsday scenario, confidence will return slowly but surely,” Dippenaar said today after the company reported a loss.
Petra held its first tender for the 2013 financial year earlier this month. Diamonds from the Koffiefontein and Williamson mines sold for more than it forecast, while prices for stones from its Cullinan and Finsch operations met company guidance.
The company, which produced about 2.2 million carats in its last financial year, said it expects output to increase about 30 percent to 2.85 million carats this year.
Petra climbed 7.6 percent to 118 pence by the close in London, the biggest gain among members of the 21-company FTSE 350 Mining Index.
The company gets most of its revenue in South Africa, where labor strikes have halted platinum and gold mines owned by Lonmin Plc and Gold Fields Ltd. Petra doesn’t see the unrest threatening its own operations because it has a smaller workforce, stable union membership and a different proportion of skilled workers, the company said.
“It’s always a concern when you see people revert to methods outside the laid-down legal procedures,” Dippenaar said. “I don’t want to say ‘Oh no, it can’t happen with us,’ because I don’t want to paint a target on our backs.”
The company today reported a fiscal full-year loss of $2.4 million, following profit of $53.2 million, on currency losses of $38.6 million.
